Pinch Analysis of the Efficiency of a Heat-Exchange System for Styrene Production

Abstract

The results of a pinch analysis of the efficiency of heat-exchange system of ethylbenzene dehydrogenation process are presented. The energy characteristics and target values of energy consumption were obtained and the utilization degree of the energy potentials of the heat-exchange system internal flows was evaluated. A potential for increasing the efficiency of thermal energy usage was estimated. Recommendations for improving the technology of the ethylbenzene dehydrogenation process were formulated based on the results, allowing an increase in the flexibility of the process, as well as the degree of its energy integration by 25%.
